You find the rune. You keep the rune. You move the rune between characters. Eventually somebody builds an Enigma and spends the next decade explaining why this was an entirely reasonable use of several hundred hours of human life.
Reign of the Warlock complicated that old arrangement by dividing Diablo II: Resurrected into separate eras. Now Blizzard is tightening the walls between them.
Starting November 16, 2026, players will no longer be able to transfer existing Expansion characters into Reign of the Warlock. Blizzard says the change is specifically intended to stop items obtained through automated farming from entering the newest version of Diablo II.
If you have an eligible old character you still want to bring forward, the clock is now ticking.
Reign of the Warlock Was Designed as a Separate Era
When Reign of the Warlock dramatically expanded Diablo II: Resurrected earlier this year, Blizzard introduced an unusual solution for preserving the old game while still allowing the expansion to change it.
Diablo II is effectively divided into three eras: Classic, Resurrected Expansion and Reign of the Warlock. Characters can move forward through those eras, but they cannot move backwards. That meant an existing Expansion character loaded with years of equipment could be transferred into the Warlock era and continue playing there.
After November 16, that final step disappears.
Blizzard's explanation is unusually direct. The studio says it wants to “close a path for items gained through automated farming to enter Reign of the Warlock” and protect a fairer experience for players.
In other words, the new era is getting a customs checkpoint.
This Is Really About Diablo II's Economy
Anyone who has played Diablo II online for long enough knows why Blizzard cares.
Diablo II's item economy is extraordinarily sensitive. High runes, perfect Uniques, charms and rare crafted equipment can represent enormous amounts of farming time, and automated farming has historically been capable of flooding that economy with items far faster than ordinary players ever could.
Reign of the Warlock added an entirely new loot ecosystem on top of that foundation, including the Chronicle collection system and new Ladder-specific item variants. Allowing an unlimited stream of older Expansion characters to carry stockpiled wealth into that environment creates an obvious problem if some of those items were acquired through automation.
Blizzard appears to have decided that preserving a cleaner Reign economy is more important than keeping transfers open forever.
Your Existing Reign Characters Are Not Being Deleted
The important thing is what Blizzard is not doing.
Characters already inside Reign of the Warlock are not being removed. Blizzard is also not announcing the end of Classic-to-Expansion progression. The specific change concerns transferring existing Expansion characters forward into the Reign era after November 16.
So if you already moved your favourite Sorceress, Barbarian or Necromancer into Reign, nothing in Blizzard's announcement suggests that character is in danger.
If you have not transferred yet, however, you now have just over a month to decide.
Reign of the Warlock Is Becoming Its Own Diablo II
This may ultimately be the more interesting part of the announcement.
When Reign of the Warlock launched, it could still feel like Diablo II with a substantial expansion attached. The lack of Legacy Graphics support already showed how separate the new era could become, while Blizzard's continued Warlock balance changes have gradually given the expansion its own identity.
Closing character transfers pushes that separation further.
Eventually, Reign of the Warlock will contain characters and an economy that largely grew inside Reign itself rather than being imported from Diablo II's older ecosystem.
There is something slightly strange about seeing Blizzard protect the economic borders of a game released in 2000.
But then Diablo II has always treated a Ber rune with roughly the seriousness other games reserve for national currency.
If you still have an Expansion character you want to bring into the Warlock era, do it before November 16.
After that, the gates close.
